Viewing Threads
If a grid node is using an unusually high percentage of the CPU for an extended period of time or if a node show signs of being unresponsive, you may consider looking at the threads in the node in order to see what is happening in the node. It could be a situation where a thread is in an endless loop or it could be in a deadlock situation.
To view threads
- Navigate to the Topology Overview page in the Grid Management pages.
- In the list, click on the name link for the node with the suspected problems.
- Click on the Advanced link.
- Click on the Threads link.
- Click on the Threads link that forms the root of the tree of threads The resulting window will list all threads and what they are doing at the moment and what state they are in.
- Refresh the window in order to see what changes over time.
